> When trying the example Python extension from here
> (https://nifi.apache.org/documentation/nifi-2.0.0-M3/html/python-developer-guide.html), copy-pasted directly into a file called WriteHelloWorld.py in the required directory I get the attached error stating:
> TypeError: FlowFileTransform.__init__() got an unexpected keyword argument 'jvm'
> The attached err.log file has more details of the error. 
> The custom processor WriteHelloWorld does show up in the list and can be dragged onto the canvas, but fails to load due to the error above.
